then you need to find that software - not defragment<br />
open task manager&gt;Performance, and hit resource Monitor<br />
then select the disk and check what's happening<br />
<br />
also - are you sure there's no virus/malware doing this?<br />
run a full AV scan, followed by :<br />

Diskeeper not DEfragmenting

Software is any set of instructions that directs a computer to perform specific tasks or operations. Computer software consists of programs, libraries and related non-executable data (such as documentation). Computer software is non-tangible, contrasted with computer hardware, which is the physical component of computers. Software written in a machine language is known as "machine code". However, in practice, software is usually written in high-level programming languages than machine language. High-level languages are translated into machine language using a compiler or interpreter or a combination of the two.

Software

Multimedia applications are those programs that integrate more than one media at a time; browsers are the most obvious. However, the term has come to include the use of programs that enable the use of any component that isn’t simple text and static graphics, such as audio, video, animation, virtual reality, conferencing and monitoring.
